ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 250,319, dated November29, 1881.

Application filed April 20, 1881.

To all whom it may concern:

Be it known that l, HENRY M. YATES, of Newark, in the county of Essexand State of New Jersey, have invented an Improvement in Roller-Skates,of which the following is a specification.

Roller-skates have been made by attaching to the runners of ordinaryskates frames carrying rollers, and these have been clamped by toscrews, so as to be removable.

My invention is for insuring more firm connection between the frame andthe skate-runner by combining with the front and back pairs of rollers abar that extends from the front to r the back pair of rollers, andinwhich is a groove for the skate-runner, which is secured by a clampingmechanism, such as a key driven in between the runner and the bar.

In the drawings, Figure 1 is a side view of the roller-carriage asattached to a skate-runner, two of the rollers being removed for showingthe frame. Fig. 2 is a transverse section at the line a: a, and Fig. 3i821. plan view.

The axles a and b are adapted to receive the 2 5 rollers c c and d cl,and these are secured by pins or keys 2 2 passing through the axles. Theframef, that connects the axles a and b, is provided with flanges it,that extend up at each side of skate-runner Z, forming a groove 0 thatis of a size adapted to receive such runner, and the groove is to bewidest at the bottom, so that the. frame is adapted to slip end- (Nomodel.)

wise upon the skate-runner; and 0 is a key or equivalent clampingdevicefor holding the carriage in place upon t-he-skate-runuer.

The runners of skates are usually the widest at bottom; hence the framewill be held more securely by the clamping device if the groove is thesame shape as the runner, and the carriage will not drop off the runnerif the clamping device becomes slightly loose.

I prefer to use keys to clamp the runner to the skate, such keys beingintroduced into longitudinal grooves in the inner faces of the flanges ii.

I claim as my invention 1. The combination, in a removable rollerskatecarriage, of front and back pairs of rollers and axles, a grooved barconnecting the axles and adapted to receive theordinary skaterunner, andmeans for clamping the bar to the runner, substantially as set forth.

2. In a removable roller-skate carriage, a grooved bur connecting thefront and back axles, the groove being widest at the bottom, incombination with a key to secure the bar to the runner, substantially asspecified.

Signed by me this 16th day of April, A. D. 1881.
